I purchased this in "yellow" and my purpose was to add it to my foundations that are too cool or too neutral to add a yellow/golden tone to them. The consistency is a bit thin.. it's not very watery and it's not too thick and creamy. I put a little foundation in my palm or on a clean surface, and add maybe 1/4 the amount of yellow and it will "morph" my foundation into a shade that suits my skin tone better. I think its great! I'll be purchasing backups and I'm thinking about ordering "white" as well to lighten any foundations that are too dark.
